According to the last revision of the standard SAE J518, we changed dimensions of the screws for flanges as follows:
- 5" series 3000 we use M16x55 and 5/8 x 2" 1/4
- 1" 1/2 series 6000 we use M16x55 and 5/8 x 2" 1/4
The standard foresees screws M12 on 1" 1/4 series 6000; we will continue to supply screws M14 standard, M12 special on request.
The technical catalogue will be modified with next issue.
